The AURORA SERIES PV modules are designed for maximizing yield in spaces where every square meter counts and ensuring stable performance in challenging conditions. The application of N-type TOPCon cells and a half-cell design helps minimize losses and maintain high efficiency even under partial shading, common in roof installations featuring chimneys, parapets, or industrial canopies with numerous lights. In practice, this translates to a more predictable annual energy production and better performance during periods of reduced sunlight.

A key feature of the series is the SMBB, or multi-busbar contact architecture, which supports uniform current flow and enhances module performance under varying temperatures. For investors, the bifacial dual glass construction is also noteworthy, prioritizing durability, environmental resistance, and long-term parameter stability.

The AURORA SERIES is ideal for premium residential installations, commercial rooftops, and ground-mounted projects where a long lifespan, reliability, and high yield without compromise are essential.

What owners get
BNEF Tier 1 – Over 20 Years in the Market

EGing PV maintains its BNEF Tier 1 status (confirmed Q2 2024), operating continuously since 2003 with an annual manufacturing capacity exceeding 25 GW. For investors, this reflects the manufacturer's demonstrated ability to honor warranties and facilitates access to project financing without additional credit enhancements.

Top Performer in 6 Test Categories (2024)

In the independent 2024 SolarChoice/PV Lab report, the series earned Top Performer recognition in six categories: thermal cycling, damp heat, mechanical stress sequence, hail stress sequence, LID+LETID, and PAN performance. This represents one of the broadest sets of validated certifications for a single series in this market segment.

Mechanical Load Rating: 5,400 / 2,400 Pa

Modules are certified for a 5,400 Pa snow load and 2,400 Pa wind pressure — ratings that significantly exceed the IEC minimum of 2,400/2,400 Pa. This enables installation in high-snowfall climate zones without additional reinforcement structures.

Up to 30-Year Power Warranty, Degradation ≤0.45%/year

The dual glass variant guarantees no more than 2% degradation in year one and ≤0.45%/year thereafter, yielding ≥84.95% of rated power output after 30 years. Peer comparables — Hiwatt Solar HW-M12/132H and ZNShine ZXM8-TP132 — offer similar peak efficiency, but long-term warranty data are not publicly available for those products.

SMBB Architecture + Dual Glass Construction

Super multi-busbar (SMBB) interconnection reduces series resistance and improves tolerance to microcracks, while the glass-glass (dual glass) construction eliminates PID risk and provides IP68-rated moisture resistance — critical advantages for ground-mounted systems and agrivoltaic applications.

Trade-offs
Series Discontinued

According to manufacturer data, the Aurora Series has been given discontinued status. This means limited availability of new modules on the secondary market, difficulty sourcing identical panels for replacements or system expansions after 5–10 years, and potential shortages of serviceable components.

P-type PERC Technology in an N-type Dominated Market

In 2024–2025, the premium segment has shifted decisively toward N-type TOPCon cells, which offer a superior temperature coefficient (approx. −0.28%/°C vs. −0.34–0.36%/°C for PERC) and lower LID. At typical summer operating temperatures (60–70°C), this translates to approximately 3–5% lower hourly energy yield compared to N-type modules in the same power class (670 Wp).

Common questions

6 answered
Is the EGing PV AURORA SERIES still available for purchase?
The EGing PV AURORA SERIES has been discontinued and is no longer actively available through standard distributor channels. If you are specifically looking for EGing PV modules, it is worth inquiring about newer product lines from this manufacturer, such as the AURORA Pro featuring N-type TOPCon technology, which offers comparable or superior specifications. Availability of remaining AURORA SERIES stock should be confirmed directly with authorized trade partners.
What warranty coverage applies to EGing PV AURORA SERIES panels?
EGing PV provides a 12-year product warranty on the AURORA SERIES, covering defects in materials and workmanship, along with a 30-year linear power output warranty. The power warranty guarantees that the module will retain a specified percentage of its nominal efficiency after 30 years of operation. This standard is typical for dual-glass modules from manufacturers classified as Tier 1.
What advantages do half-cut cell and SMBB technologies offer in the AURORA SERIES, and are they worth the additional cost?
The half-cut cell design splits each cell into two, reducing resistive losses and improving tolerance to partial shading caused by chimneys or dormer windows. SMBB (Super Multi Busbar) increases the number of current conduction paths, lowers internal resistance, and enhances light reflection across the cell surface. The result is a higher annual energy yield, particularly noticeable under variable irradiance conditions or on rooftops with shading elements.
What is the maximum power output of an EGing PV AURORA SERIES panel, and what does that mean in practice?
The highest-rated model in the series achieves a peak power output of 670 Wp, measured under Standard Test Conditions (STC: 1000 W/m², cell temperature 25°C). Under real-world conditions, actual energy production depends on azimuth orientation, tilt angle, module temperature, and local solar irradiance. At 670 Wp, the series falls within the large-format module category, designed for commercial and industrial installations where power density per square meter of roof or ground area is a critical factor.
Are EGing PV AURORA SERIES panels suitable for a roof with chimneys or dormer windows?
Yes. Thanks to the half-cut cell architecture, the AURORA SERIES handles partial shading significantly better than legacy full-cell modules, because shading or damage to one half of a cell does not eliminate output from the other half. However, on rooftops with multiple obstructions — chimneys, dormers, antennas — it is still advisable to consider power optimizers or an inverter with independent per-string MPPT tracking in order to maximize yield from a complex roof layout.
Is EGing PV a reliable manufacturer, and can I be confident that warranty claims will be honored?
EGing PV holds Tier 1 status according to the Bloomberg NEF ranking, which confirms the company's financial and manufacturing stability. The manufacturer has been operating for over 20 years and supplies modules to projects worldwide. Tier 1 classification is also a common requirement from banks and financial institutions funding photovoltaic investments. That said, warranty fulfillment also depends on the terms agreed with the local distributor, so it is advisable to verify that the distributor provides warranty support within Poland.
